Solve: 800+0?800-0 | Finding the Missing Digit in a Number Sequence

$800+0?800-0$

To solve the problem $800 + 0 ? 800 - 0$, follow these steps:

• Step 1: Calculate $800 + 0$. Using the identity property of addition, we get $800 + 0 = 800$.
• Step 2: Calculate $800 - 0$. Similarly, using the identity property of subtraction, we get $800 - 0 = 800$.
• Step 3: Compare the two results, $800$ and $800$.

Since both sides yield the same value, $800 = 800$, we use the equality symbol $=$ to indicate they are equal.

Therefore, the correct relation is $=$, which corresponds to choice 3.
